The province's chief coroner, Denis Marsolais, will preside over the inquiry.

Alain Magloire, 41, was shot and killed following 911 calls about an assault with a hammer.

He's the third mentally ill man Montreal police have gunned down since 2011.

"Given that some emergency interventions...involving people with mental health problems have resulted in deaths in recent years, it is appropriate to conduct a public inquiry," the coroner's office said in a statement.

A Quebec corner has already criticized Montreal police for inadequate training and infrequent use of Tasers.

The report released in May 2012 highlighted poor pistol training after a stray bullet killed bystander Patrick Limoges during a botched takedown the previous year.

A mentally ill man armed with a knife was also killed in the operation.
